Whatever the value for \(\delta =\pm 1\) , and depending on the value for the ModMax deformation parameter \(\gamma \ge 0\)  contributing through the sole
quantity \(e^{\delta \gamma }\)  involved in these expressions, these field configurations display the following behaviour when \(\gamma \)  is turned on.
The closed and linked \(\vec{E}\)  and \(\vec{B}\)  field lines of the ordinary HR solution at \(\gamma =0\)  are then each split, when \(\gamma \ne 0\) , into
pairs of closed and linked \(\vec{D}\)  and \(\vec{E}\) , on the one hand, and \(\vec{B}\)  and \(\vec{H}\) , on the other hand, field lines, of which some
of the 3-vector components have some of their contributions rescaled by the factor \(e^{\delta \gamma }\)  and this in a manner dependent both
on the considered point \((X,Y,Z)\)  in space and on which field is being evaluated.
In other words, as compared to their configuration when \(\gamma =0\) , when \(\gamma \)  is turned on all field lines are
tilted and twisted in this or that direction in space in a manner dependent on the point in space which that field line is crossing —
yet by maintaining however, the topologically nontrivial loop structure of all these closed field lines which, for \(\gamma =0\) , wind around
embedded circular torii all sharing the \(Z\)  axis as a common rotational symmetry axis[1]}, [2]},
these torii thus being deformed by twisting and squeezing when \(\gamma \ne 0\)  while preserving their embedded topology to still fill up all of space.
In particular what would be a \(\pi /2\)  circular rotation symmetry around the \(Z\)  axis when \(\gamma =0\) , is deformed
when \(\gamma \ne 0\)  into a shape that reminds one of an elliptic-type deformation along certain principal axes (given the above expressions at \(T=0\) 
this is easiest to visualize in the \(Z=0\)  plane). This feature of these ModMax deformed HR knots is the analogue of what happens
for transverse circularly polarised travelling plane waves for \(\gamma =0\)  being deformed into elliptically polarised ones when \(\gamma \ne 0\) ,
as pointed out[3]} in Sect.REF .
